SECTIONAL BOILER.

SPECIFCATION forming part of Letters Patent No. 366.248, dated July 12,1887.

Application filed May 14, 1887.

To all whom it may concern.-

Be it known that we, CHARLES PLAxToN, of the city of W'innipeg, inthecounty of Selkirk, in the Province of Manitoba, Canada,

plumber, and JOHN PLAxToN, of the town of Barrie, in the county ofSimcoe, in the Province of Ontario, Canada, plumber, havejointlyinvented certain new and useful Improvements in Hot-rater SectionalBoilers, ot' which the 1o following is a specification.

rlhe object of the invention is to design a simply-constructed hot-watersectional boiler in which the water will flow to and fro through smallcompartments, each compartment arranged in the furnace and practicallysur rounded by the flames, so that it shall be quickly heated andextract to the fullest extent possible the heat of the flames; and itconsists of a series of sections extending from the zo firepot to thetop of the boiler, each section having a series of hollow projectingfingers extending across the furnace, a dividing-pan tition being placedin each finger, so as to separate the water flowinginto the bottom sideof the linger from the water flowing out of the top side of the saidfinger, the sections l being arranged in pairs opposite to each other,

the lingers of one section projecting between the ingers of its oppositemate, the whole 5o being arranged and constructed substantially ashereinafter more particularly explained.

Figure l is a perspective view of our improved furnace with one of thesides removed to expose the interior arrangement of the iingers. Fig. 2is a vertical cross-section through the line ac y of Fig. 1. Fig. 3 is asectional detail of one of the sections.

In the drawings, A represents a series of hollow vertical sections, eachsection being provided with ahollow finger, B, projecting across thefurnace, as indicated.

It will be noticed that the hollow sections A are arranged in pairsopposite to each other, the ingers of one section extending between 4.5the fingers of the opposite section, forming a zigzag ilue, O, extendingfrom the fire-pot D to the top of the boiler, where the smokefiue E islocated. Consequently the flames and heated gases ascending fromthefire-pot D 5c practically surround each of the hollow fingers SerialNo. 238,248. (No model.)

B, and as each of these lingers contains but a small body of water theeffect of the flames is immediate and effectual.

Each of the sections A may have an independent inletpipe, F, and anindependent 5 5 outlet-pipe, G, but,if desired, chambers at H and I maybe formed, so as to connect all the sections A together at their top andbottom, it being merely necessary to form suitable joints between eachsection. The water which enters the inlet-pipe F passes up through eachsection A, but in doing so must flow through each of the fingers Bbelonging to its respective section, a partition, J, being placed ineaehfinger B for the purpose of separating the water entering the ngerfrom the water flowing back out from it.

A boiler constructed of sections formed in the manner described will bevery cheap to produce, as there is practically no fitting re- 70 quired,the numberof sections required being arranged and secured together bythe front and back plates, K, which are secured together by suitablebolts extending from one plate to the other.

It will be seen that the size of the furnace may be increased ordecreased, as required, by

simply adding additional sections or removing such as are not wanted.

As the action of the flue O will naturally have a tendency to cause astronger upward draft in the rear of the furnace, immediately below itwe place a slanting partition, M, by which partition we cut oft' thefine immediately next to the rear section, and thereby equalize thedraft through the entire furnace.

It will be noticed that the tlues O may be readily cleaned by simplyremoving one of the plates, as shown in Fig. l.

Vhat we claim as our invention is- 9o l. A hot-water boiler composed ofa series of hollow sections, A, having horizontally projecting hollowlingers B formed on each section, which sections are arranged in pairsopposite to each other, so that the iingers of one section shall projectbetween the iingers of the section opposite to it, forming a zigzagtlue, C, substantially as and for the purpose i specified.
